I think the one post said only the 1.9 engines got them and the 255 still has the 1.8’s.Was there confirmation somewhere that the 255 was coming with a 4-blade impeller? I thought I read someone say that, but I can't find anything on it.
After watching those videos......I challenge anyone to tell me a jet isn't as maneuverable as something else. The best part is, the only capability the joystick has over the regular twin engines is the ability to split the steering between jets, otherwise the SX210 has the same control as that setup.
That’s a great video thanks for posting!After watching those videos......I challenge anyone to tell me a jet isn't as maneuverable as something else.

Cool stuff.
@HangOutdoorsThis is a great video going over the details of the new engines if anyone is interested. Around 17 minutes is where the details start.
I saw it and watched it
Except that there is a new Rotax engine for 2024, https://jetboaters.net/threads/new-325-hp-rotax-for-2024.42465/The older 1.8L was originally designed with the intent to make max power without forced induction, and the addition of super charging came later (? That’s my impression) as a way to boost power. Having said that, I think what we may be looking at is higher power from the SC’ed 1.9L over the 1.8L, I’m going to guess the power will be increased to 300 hp or slightly more so that Yamaha will be the HP king over Rotax powered Scarabs and their 300 hp engines.
That's kind of the most important part.the only capability the joystick has over the regular twin engines is the ability to split the steering between jets
I would anticipate big things for the redesign of the 25'. Have a funny feeling it is going to have some very good things. When that day comes.I hope the next redesign of the 25' is like the 22' so the bimini top does not need a cage. I really like how I can roll up my bimini and just have the wake tower.
The 1.8L HO and 1.8L SHO were released alongside each other in 2008 in the FX Cruiser HO and SHO and FZR/FZS SHO in 2009. The boats were still running the MR-1 and didn't have the 1812cc engine until 2010 IIRC. The 1.8L engine was not designed as a NA motor with supercharging thrown in as an after thought especially since Seadoo was running SCers in the GTX since 2003 and RXP since 2004.The older 1.8L was originally designed with the intent to make max power without forced induction, and the addition of super charging came later (? That’s my impression) as a way to boost power.
That all sounds fantastic, I was itching to go after the 255 FSH Sport H this year, but maybe I can hold my trigger finger another year and perhaps they'll have SVHO 1.8's in them next year... that would be worth waiting for I think.I got a 2024 AR250 in yesterday and was able to get it out on the water today. Here are my impressions of the new motors:
- The engines definitely have more power than the previous 1.8. It was very noticeable on take off and in the mid range. We had two full size adults on board and hit 51 mph. There was no cavitation on a full power take off from standstill and the boat really hooked up well. I'm very pleased.
- Noise wise the boat is certainly quieter. At 30mph I was able to hold a normal level conversation with my tech. Of course there's still wind noise but the drone of the engines is significantly less.
- Vibration levels have been drastically improved and honestly that was my and my tech's biggest take aways from our outing this morning. There was not rattling throughout the boat and the steering wheel and throttles felt absolutely solid and still. It really feels like an entirely different boat.
I didn't do much efficiency testing but with a full tank of fuel and 2 large men aboard we were getting just 12.7gph at 29/30mph. Not too shabby. Happy to answer any questions so fire away.
